File Description:This has revised runway circulation for both Dutch Harbour (dutchplus.zip) and St Paul (st_paul.zip) to better reflect reality in helicopter and aircraft operation. It is not realistic for a helicopter to land, continue in a straight line along 6,000' of runway, turn at the far end, then taxi back along the same 6,000' to the aprons. Similarly, a Cessna does not need the same runway length as a 747.

This fix incorporates intermediate turnaround points to allow helicopters and small aircraft to turn around soon after slowing to taxi speed and to taxi back to the aprons at the end of the runway, instead of trudging along the whole length of the runway twice. There are some things that cannot be improved; a plane or helicopter will always taxi all the way from the aprons to the far end of the runway before turning and taking off, and a helicopter or light plane will not "land long" to minimise the taxi length.
The pictures show different turning points. There are also revised AI bgl's to provide better time separation between flights.
